Need help

Ok when driving my truck get off the line ok revs up then goes and sometimes just bogs then have to let off but when I'm trying to do some hs runs I can only pull the about 3/4 throttle if I go full it also bogs any suggestions

sounds like a lean hsn!

my pro .15 did that it had a clutch problem. if the clutch doesn't engage it boggs never under stood why

I have made it richer and Leaned it out according to the flow chart if it bogs then you lean the hsn so idk

Change glow plug. Then set carb back to factory settings and retune from there going by the chart. Clutch shouldn't be causing it to bog but just the opposite. If clutch isn't engaging it will free rev or slip under torque just like a car.

but when they rev to high they shut out. my ten year old pro .15 always did that( the engine was crap)

There are 2 different types of bogs, Rich & Lean.

If you can run ok at ¾ throttle but the engine bogs at full throttle the engine is starving of fuel due to a lean HSN or an air leak.

I'm gonna try and take it out tomorrow been raining off and on all day and what if it bogs off the line

Seal it if you haven't already. Then tune er in.
